' OIL Bunmm.

This invention relates to an oil burner and amon the objects of the invention are to provide a burner which efficiently burns raw and ungasified liquid fuel quietly, economically and without the generation of 'odors or smoke. Practically any kind of oil may be used and the oil is' consumed without forcing the fuel to the burne'rs under pressure and utilizing any movingmechanical devices within the conbustion chamber. Flooding is elininated and complete conbustion is hadwithout danger of ,back-firing and with a minimum fire hazard. A maximum degree of heat is generated so that practically all of the available heat units are had of the'oil supply.

A further object is to provide an oil burner which is' of simple and durable construction reliable and effective in operation and easy and comparatively ineXpensi-Ve to install, operate and maintain.

Other objects and advantages reside in certain novel features of the Construction, arrangement and'combination of parts which 4 will' be herenafter more fully described and particularly pointed out in the appended claim, reference panying drawings forming a part of this specification, and in which Figure 1 is a View in elevation illustrating the burner installed in the furnace o` a heating plant, e Figure 2-is a plan view of the burner, Figures 3 and 4 are sectional views on the li-'ne 3-3 and 4-4, respectively,' of Figure Fi ure 5 is a view in transverse section on the lne 5-5 of Fgure 2.

Referring to the drawings it will be seen that the burner comprises a tubular body B which may be of any desired shape but which is shown as consisting of: side bars. 1 and 2, end bars 3 and 4 and an' intermediate bar 5 connectng the end bars 3 and 4. r All' of the tubular bars of the frame are hollow and have an internal portion 7 which di- 9 for the compressed air. Each carries a lurality ofburners, there being burners esignated generallyr` at 10 and burners designated. generally at 11. --The burners 10 have body portion'sawhich extend through the passages andhate their inner'ends 13 threaded 'through the partibeing had to the accombody but, of course,

titition 7 'and' the outer wall of the hollow bar to limit the extent to, which the body of the burner may be screwed into the bar. It' desired gaskets may be interposed between the shoulders and the parts with which they co-act. The body 12 of each burner is provided with an axial opening 16 which communicates with the fuel oil passage 8 and which leads out through the performed boss 17. u\ pluralityot' air supply passage 18 are provided and are radially spaced from the fuel supply passage 16. The passages 18 communicate at one end with the air supply passage 9 and through the opposite ends that discharge 'around a perforated boss 17. The discharge ends of .the passages 18 and the perforated boss 17 are located within a tip or cap 20 having a flange 21-threaded on the'body portion 12 and held in adjusted position thereon by means of a nut 21. At its outer end the cap 20 has an inclined wall 23 which converges to a jet opening 24:

aligned with the opening of the boss 17. The boss 17 has its outer end rounded ot, as indicated at 17 so that the' air that flows out through 'the passages 18 is caused to traverse the outer end of the jet and to entrain and atonize the t'uel oil, the air serving to pull the fuel oil through the passage 16 from the passage 8. a y

'The nozzles 11 have clongated body portions 30 threadedly connected, as at 31, with the body of the hollow bars and' threadedly connected, as at 32, with the partitions. In this form it may be desirable to employ only one shoulder 33 engageable with the hollow the shoulder may be provided to engage the partition 7 'f this is desirable. As before gaskts may be employed beneath the shoulders. The elongated ody portion 30 has a single fuel passage 35 extending therethrough and the outer end of this body portion'is bent over and extends horiz'ontally, as indinated at 36. The hori- `zontally extending portion 36 earries a tip 37 which has a restricted discharge passage 38 overlying: a nozzle 39 serewed into the 'body portion of thebar and having an opencommunicates with the The discha 'e end of thedischargeopening' of the tip 37 and entrans and atomzes the liqud fueL at-41, and is' `As shown in Figura 1 the passages 9 of the hollow body of the burne'r are provided with air-under press ure froma blower 40 driven by a motor 41 and supplying the air line 42. This same blower may supply air for combustion through an air duct 43' leading up into the combustion chamber and This pump is operated `frena a motor 41 and pumps the oil slowly through a fuel 1111957. The oil when flowing into the passage 8 exists under atinospheric pressur and the level of the oil is determined by means of an overflow 59 communicating with the hollow passages 8 at the desired level and leading back through a safety switch 60 from which a line 66 returns to the fuel supply tank. When the fuel level exceeds a predetermined height in the passages 8 or in the fuel supply. passages 16 or 35 the switch is automatically operated to cut ofi the fuel supply pump. The manner in which this operates is conventional and as these details form no part of the present invention they need not be set out in this application. I

For the purpose of faclitating starting, a. gas line 70 leads to the furnace and terminates in a gas tip 71 adjacent the burner.-

` We claim 1- A burner comprising ahollow frarne having a parttion therein defining an air supply passage and a fuel supply passage, an elongated burner body threadedly connected with the frame and with its parttion and 'having a passage extending therethrough communi- 'cating with the fuel supply passage, the outer end of the body being angularly extended and providedwith a tip; and a nozzle connected to the frame and'communicating With the air supply passage and having a passage therein dischargng adjacent the tip'whereby the fuel is entrained and atomized.
